Thinking about getting a Premiere4 and moving the cablecard from my Premiere to the 4. The Premiere would then be OTA only. Any issues or concerns with streaming between them (will cablecard channels be copy protected and unwatchable on the original Premiere?)

Although when I sold my last Lifetime Premiere, I put the cable card from that box in my monthly Premiere which was OTA only. When I get an IP STB that Premiere will go back to OTA only and I will turn in that cable card to save $4 a month of my FiOS bill.

I'd assume no issue - but want to make sure.

You can stream to your hearts content. Transferring is where you have copy protection issues
